7.1 Notes on installation

The following tips and instructions must be observed wile installing the air

conditioning roof unit:

!



Before installing the parking cooler, check whether any vehicle components

could be damaged or have their function impaired as a result of the installa-

tion.

Check the dimensions of the system to be installed (fig. 2).

The dotted line indicates the middle of the roof hatch opening.



Before installation, find out (by consulting the manufacturer of the vehicle)

whether the construction is designed for the static weight and the loads of

the parking cooler when the vehicle is in motion. The manufacturer of the air

conditioning roof unit assumes no liability whatsoever.



The roof inclination of the mounting surface may not exceed 8° in the

direction of travel.



The supplied assembly parts must not be modified during installation.

CAUTION!

Improper installation of the air conditioning roof unit can result in irreparable

damage to the device and put the safety of the user at risk.

The manufacturer will not be held liable for claims if the air conditioning roof

unit is not installed according to this installation manual. That applies to mal-

functions and the safety of the air conditioning roof unit, in particular to injuries

and damage to property.

NOTICE!



The air conditioning roof unit may only be installed by qualified personnel

from a specialist company. The following information is intended for

technicians who are familiar with the guidelines and safety precautions to

be applied.



The manufacturer only assumes liability for parts included in the scope of

delivery. The validity of the warranty expires if the device is installed

together with third-party parts.



Check whether the roof of the vehicle is able to support the weight of a

person before climbing onto it. Ask the vehicle manufacturer about the

permitted roof loads.

WARNING!

Make sure that all electrical components are electrically discharged before

carrying out work on them.

Before installing the parking cooler, disconnect all connections to the vehicle

battery.



The ventilation slots (grill) may not be covered (minimum distance from other

attachment parts: 10 cm).



You can connect the unit to the battery via the lorry's terminal block or

directly. The terminal block is to be preferred for the connection. On some

vehicles, larger consumers connected to the terminal block are switched off

after a short while if the power requirement is too high. Ask your vehicle

manufacturer for the specifications of the terminal block.



When installing the system and making the electrical connections, observe

the guidelines from the body manufacturer.

7.3 Creating an opening (if necessary)

I

➤ Create an opening with the dimensions 505 mm x 500 mm and a corner

radius of R25 (fig. 7, arrow = direction of travel).

I

7.4 Attaching the seal for the cab roof

A

➤ Stick the insulating tape to the cab roof (fig. 8):

➤ Provide the abutting edge and the top edge of the insulating tape with an

unhardened plastic butyl sealing compound (e.g. SikaLastomer-710).

7.5 Preparing the unit (RT780 only)

A

Proceed as follows (fig. 9):

➤ Place the air conditioning roof unit on a work surface with the housing facing

down.

➤ Screw in the self-threading thread inserts in the corresponding blind holes.

NOTE

A template has been integrated in the packaging to enable an opening to be

created simply.

NOTE

Dispose of all waste materials separately. Observe the local disposal guide-

lines.

NOTICE!

Ensure that the adhesive surface for the seal between the unit and the cab roof

is clean (free of dust, oil, etc.).

NOTICE!



During preparatory work on the surfaces, secure the unit from falling down.



Make sure that the work surface is clean and level to ensure that the unit is

not damaged.



Do not exceed the specified torque under any circumstances. This is the

only way to ensure that the thread inserts are not torn out.

A

➤ Fix the parking cooler in place as illustrated (fig. a)

➤ Determine the length of the hex screw M8 required for securing the

installation as shown in fig. c:

Screw length = distance between the bottom edge of the fastening bar and

the bottom of the unit plus 5 mm). If necessary, shorten the hex screw to the

size determined.

NOTE

Make sure the air conditioning roof unit is centred perfectly. The seal must be

applied continuously around the air conditioning roof unit after being placed

on the roof of the vehicle. This is the only way to ensure a tight seal.

NOTICE!

The fastening holders must be positioned on a firm surface, since the unit will

be pushed against the cab roof by the holder. The contact surface of the fasten-

ing holder must be at least 40 mm on all sides.

NOTICE!

Do not exceed the specified torque under any circumstances. This is the only

way to ensure that the thread inserts are not torn out.

7.7 Installing the electrical supply lines

!

A

I

You can connect the unit to the battery via the lorry's terminal block or directly.

The terminal block is to be preferred for the connection. Ask your vehicle

manufacturer for the specifications of the terminal block.

Proceed as follows (fig. 5):

➤ Lay the supply line and connect it to the vehicle (red line to plus, black line to

minus).

➤ Plug in the supply line plug into the socket of the air conditioning roof unit

supply line.

➤ To relieve strain on the supply line, secure it with a cable tie, e.g. to the cab

roof.

WARNING!



The electrical power supply may only be performed by qualified personnel

with specialist knowledge.



Make sure there is no voltage present on electrically operated components

before carrying out work on them!

NOTICE!



Fit a fuse of 25 amps to the connection to the vehicle's power supply.



The battery must be able to supply the required current and voltage

(chapter “Technical data” on page 21).



Cut the connection cable to the shortest possible length. Otherwise the

voltage drop is increased and thereby the air conditioning roof unit‘s

performance reduced.

NOTE

The unit is equipped as standard with a 4 m long cable with a cross-section of

6mm

2

. If longer cable lengths are required, then the cable cross-section must

be increased by an authorised specialist workshop:

In this case cut off the cable as closely as possible to the unit (max. 0.5 m) and

then establish a suitable connection with a larger cable cross-section.

When the cable is extended by 4 m to 6 m in length, the manufacturer

recommends using a cross-section of at least 8 mm

7.8 Installing supply lines to the condenser unit

(SP950Tonly)

Observe the following instructions when installing the supply lines:



Also observe the installation instructions for the condenser unit.



The maximum cable length between the evaporator and condenser unit is

4.20 m (fig. e).



When installing and bending supply lines, avoid narrow radii. Use a suitable

round object as a bending aid. A radius which is too narrow will buckle the

refrigerant line, and the parking cooler will be inoperable.

➤ Shorten any supply line which is not needed by bending a curve.

➤ Apply packing compound (fig. e 1) to prevent water entering between the

rear wall of the truck and the clip.

I

➤ Fasten the supply lines to the rear wall of the truck using the clips provided

(fig. e).

➤ Insert the corrugated piping in the holder provided (2).

➤ Put the cover on (fig. e 4).

7.9 Adjusting the cover frame

When installed, the outlet unit must protrude approx. 6 mm over the cover

frame.

➤ Cut the cover frame to suit the properties of the vehicle (fig. c).

7.10 Fastening the cover frame

A

➤ Fix the cover frame in place as illustrated (fig. d).

NOTE

If you wish to avoid damaging the rear wall of the truck (drilling a hole), you can

also apply the clip using a suitable adhesive. Observe the instructions provided

by the adhesive manufacturer.

NOTICE!

Screw the screws in carefully order not to damage the cover frame.

8 Configuration of unit software

Before you first start up the unit, the controls can be adapted to suit the

installation conditions. This must be done by the person installing the unit.

In configuration mode, the following unit software parameters must be set at the

control panel (fig. 4):

8.1 Starting and ending configuration mode

The adjustable parameters can be changed in configuration mode:

➤ When using the button to switch on the unit, hold both buttons +

✓ You are now in configuration mode.

✓ The display version (e. g. “3.1S”) appears in the display for 2 seconds.

✓ The first digit of the display shows the menu level and the second and third

digits show the parameters which can be set, e.g.

1.17 for menu level 1 and a

set target value of 17 °C.
